Plastic container

Abstract

Plastic container (1) being composed of a neck (3), a shoulder (5), a body (4) and a base section (2), where the base section (2) comprises at least two tie members (6a) extending from a central area (8) to the side wall of the base (2). According to the invention, the tie members (6b, 6c) and/or the function of the tie members (6b, 6c) of the base (2) at least in certain areas extend into the body section (4) or into the body (4) and the shoulder section (5) of the plastic container (1).

What is claimed is: 
     
       1. A plastic container comprising:
 a neck section, a shoulder section, a body section, and a base section, wherein the base section includes at least two tie members extending from a central area to a side wall of the base section, the at least two tie members formed as partial grooves that extend in a longitudinal direction and arranged between feet of the base section; and 
 a plurality of circumferential grooves oriented in a peripheral direction and having a varying depth between the at least two tie members, 
 wherein the at least two tie members end before a labeling area of the body section intended for receiving a label, and 
 wherein the labeling area includes a plurality of peripherally constant depth grooves. 
 
     
     
       2. The plastic container of  claim 1 , wherein the at least two tie members extend in a longitudinal direction on a periphery of the container from the base section towards the neck section. 
     
     
       3. The plastic container of  claim 1 , wherein the base section comprises at least two feet and the number of feet is a multiple of the number of tie members. 
     
     
       4. The plastic container of  claim 3 , wherein for two tie members, there are two, four, six, eight, ten, or twelve feet and for three tie members, there are three, six, nine, or twelve feet. 
     
     
       5. The plastic container of  claim 1 , wherein the tie members extend transversely to the circumferential grooves. 
     
     
       6. The plastic container of  claim 1 , further including at least one reinforcement groove between the at least two tie members, the at least one reinforcement groove having a varying depth in a radial direction. 
     
     
       7. The plastic container of  claim 1 , wherein the base section further includes a central dome, a first region, and a second region, the first region adjacent the central dome and having a first radius of curvature greater than the central dome, the second region adjacent the first region and having a second radius of curvature greater than the first radius of curvature. 
     
     
       8. The plastic container of  claim 1 , wherein each groove of the plurality of circumferential grooves has a first depth at a first location such that the plurality of circumferential grooves functions as one of the at least two tie members. 
     
     
       9. The plastic container of  claim 8 , wherein each groove of the plurality of circumferential grooves further has a second depth at an intermediate area, the first depth being shallower than the second depth. 
     
     
       10. The plastic container of  claim 1 , wherein the base section further includes a central dome, and wherein at least one of the at least two tie members extends from the central dome. 
     
     
       11. The plastic container of  claim 1 , wherein the labeling area is free of peripherally variable depth grooves.
